Tests And Diagnosis For Prediabetes
Your doctor will do at least one of these tests:
Fasting plasma glucose test. You wonât eat for 8 hours, and then a technician will take your blood to test the sugar levels. The results are:
- Normal if your blood sugar is less than 100 milligrams per deciliter
- Prediabetes if your blood sugar is 100 to 125 mg/dL
- Diabetes if your blood sugar is 126 mg/dL or higher
Oral glucose tolerance test. First, youâll have a fasting plasma glucose test. Then, youâll drink something sugary. Two hours after that, a technician will take and test more blood. The results are:
- Normal if your blood sugar is less than 140 mg/dL after the second test
- Prediabetes if your blood sugar is 140 to 199 mg/dL after the second test
- Diabetes if your blood sugar is 200 mg/dL or higher after the second test
Hemoglobin A1c test. This blood test shows your average blood sugar levels for the past 2 to 3 months. Doctors give it to people who have diabetes to see if their blood sugar levels are under control. They can also use it to diagnose prediabetes or diabetes. The results are:
- Normal if itâs 5.6% or less
- Prediabetes if itâs 5.7 to 6.4%
- Diabetes if itâs 6.5% or above
You may need to take the test again to confirm the results.

Treatment By Family Friends Or Co
Family, friends, and co-workers of those with hypoglycemia are often first to identify hypoglycemic episodes, and may offer help. Upon recognizing the signs and symptoms of hypoglycemia in a diabetic, a blood sugar level should first be measured using a glucose meter. If blood glucose is below 70 mg/dL , treatment will depend on whether the person is conscious and can swallow safely. If the person is conscious and able to swallow, the family, friend, or co-worker can help the hypoglycemic consume 10-20 grams of a carbohydrate to raise blood glucose levels to a minimum of 70 mg/dL . Improvement in blood sugar level and symptoms is expected to occur in 1520 minutes, at which point blood sugar is measured again. If the repeat blood sugar level is not above 70 mg/dL , the hypoglycemic should consume another 10-20 grams of a carbohydrate and with remeasurement of blood sugar levels after 1520 minutes. Repeat until blood glucose levels have returned to normal levels, or call emergency services for further assistance.
If the person is unconscious, a glucagon kit may be used to treat severe hypoglycemia, which delivers glucagon either by injection into a muscle or through nasal inhalation. In the United States, glucacon kits are available by prescription for diabetic patients to carry in case of an episode of severe hypoglycemia. Emergency services should be called for further assistance.
How Can I Be Better Prepared For Hypoglycemia
You can take some steps to be ready for hypoglycemia:
- Be aware of the symptoms and treat them early.
- Carry some fast-acting carbs with you all the time.
- Check your glucose levels frequently, especially around meals and exercise.
- Inform family, friends and co-workers so they know what do if you need help.
- Talk to your healthcare provider regularly to make and update your plan.
- Wear a medical bracelet that lets people know you have diabetes. Carry a card in your purse or wallet with instructions for hypoglycemia.
A note from Cleveland Clinic
Hypoglycemia is quite common in people with diabetes. If not treated, it can cause troubling symptoms, and even serious health problems. Fortunately, you can avoid hypoglycemic episodes by monitoring your blood sugar. You can also make small adjustments to eating and exercising routines.

What Else Should I Ask My Healthcare Provider
If you are at risk for diabetes or prediabetes, ask your healthcare provider:
- What is my blood sugar level?
- What steps can I take to lower my blood sugar level?
- How often should I get my blood sugar checked?
- What else can I do to prevent Type 2 diabetes?
A note from Cleveland Clinic
Prediabetes is a common condition. It means your blood sugar levels are high but not high enough to be considered diabetes. You may not have any prediabetes symptoms. Its important to talk to your healthcare provider about getting regular blood tests, including an A1C test, especially if youre high risk.
The good news is that you can reverse prediabetes. Losing weight and exercising, along with other lifestyle changes, can bring your blood sugar levels back to a healthy range. Talk to your healthcare provider about how you can prevent or delay Type 2 diabetes.

How Do You Treat Hypoglycemia

Low blood sugar levels happen when theres too little glucose left in the bloodstream to continue supplying fuel to your organs, muscles, and tissues. It most often occurs when you dont eat enough food, especially carb-containing foods, given your blood-sugar-lowering medications and physical activity levels, ONeill says. Levels can decrease gradually or suddenly.
When the amount of glucose in the bloodstream drops to too-low levels, the body reacts by releasing epinephrine, also called adrenaline or the fight or flight hormone. Epinephrine revs your heart rate and can cause sweating, shaking, anxiety, and irritability. If not enough glucose is able to reach the brain, the result may be difficulty concentrating, confused thinking, and slurred speech. In extreme cases, a lack of glucose within the brain can lead to seizures, coma, and even death, she says.
People with low glucose levels can use the ADAs 15-15 Rule, which advises people consume 15 g of carbs, wait 15 minutes, and check their levels again. If the number is still low, repeat until reaching at least 70 mg/dL.
You can find 15 g of carbs in:
- 1 slice of bread
- Three to four hard candies
- Glucose tablets as indicated on the label
- Glucose gel as indicated on the label
Once your glucose levels are back to normal, the ADA suggests going ahead and eating your next scheduled meal or snack, which will help prevent levels from dropping again.

To manage stress, try any or all of these things:
- Yoga or tai chi
- Meditation
- Keep a gratitude journal
- Use adaptogenic herbs like Tulsi or one of my favorites Ashwagandha
Adaptogens are a class of herbs that help your body adapt to various types of stressors. They have long been used in Ayurvedic medicine. Tulsi is one of my favorites and it happens to be another ingredient in Herbaly Wellness Collection tea.

- The symptoms of low blood sugar and how to tell if you have them.
- How much and what kind of food they should give you.
- When to call for emergency help.
- How to inject glucagon, a hormone that increases your blood sugar. Your provider will tell you when to use this medicine.
If you have diabetes, always wear a medical alert bracelet or necklace. This helps emergency medical workers know you have diabetes.
Nighttime Low Blood Sugars
You may experience a low blood sugar night. The low blood sugar might wake you up and your symptoms might be similar to those you have during the day. However, the symptoms may be different. You might have nightmares, sleep poorly, perspire, or feel hot and cold. In the morning you may have a headache, feel nauseated, or feel confused. Notify your doctor if this happens. Check your blood sugar at the time you have the symptoms.
Treatment for a low blood sugar that occurs at night is the same as described earlier.
Your doctor may request that you check a 3:00 a.m. blood sugar 1 to 2 times per week in order to detect any low blood sugars during the night.

Treating An Episode Of Hypoglycaemia
The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.
For example, this could be:
- a glass of fruit juice or non-diet soft drink
- between three and five dextrose tablets
- a handful of sweets
At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.
After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.
It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.
When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.
It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.

No Symptoms Be Alarmed
Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.
